v]![ACIII1\TE FOR MAKlNG CAPSULES.

To all whom it may concern:

-Be it known that we, ARTHUR CoLToN and BURTON -W. SCOTT, citizens of the United States, residing at Detroit, in the county of Wayne, State of Michigan, have invented certain new and useful Improvements in Machines for Making'Capsules; and we do declare the followin to be a full, clear, and exact description o the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom anying drawings, and to the figures of re erence marked thereon, which form a part of this specification. I l

This invention relates to a capsule machine, and consists in the construction and arrangement of parts hereinafter more fully set forth and pointed out particularly in the claims.

The primar object of the invention is to produce a mac ine of the character described, wherein the arrangement is such as to facilitate the feeding of the bodies and caps of the capsules 'into the machine upon the molding pins, o n which they are formed, stripping the bodies and caps from said pin-s, an trimming them to render them the prop el' size, joining the bodies and caps and dis.- charging the'completed capsules from the machine.

A further object is to provide means for greasing the pins after the bodies andl caps eiiicie'ntfmeans for driving. the several .groups of operative parts` in timed relation to attain the results desired. The above objects are accomplished through ical parts illustrated in the accompanying drawings, in which Fi ure l is a plan yiew of a machine embodying our invention.

In effecting an embodiment of our invention in an operative machine, as shown herein, we found it desirable tomountthe mold pins 1 and 2 (whereon the bodies and capsy respectively of the capsulesare formed by dipping said bodies in a bath of gelatin, as

other.

will be well understood inthe art) in bars 3 and 4 of suitable len h, wherein said pins are arrangedv in per ect alineinent and are spacedV vthe requisite distance from one anv These bars are introduced respectively intovertical guides-5 and 6 arranged .on o posite sides of the machine andl carried by t 'e frame-thereof, wherein said bars -are fed intermittently and simultaneously downward in pairs to resent the projecting pins l in each sequential y in fposition to permit the stripping therefrom o the -bodies and caps of the capsules and the introduction of said bodies and caps into their respective receiving sockets in the carrier disks.

ding the pin bars As the mechanism for f 3 and 4. downwardly in their respective C guides 5 and 6 is the same, the explanation mechanism will be made withreference to of the construction and operation of said that set employed in feedin vthe bars 3 downwardly in the ways. 5, with the understanding that said description a plies .also

'to the mechanism employed for ceding the bars 4 in the-guide 6.

On referring to Figs. 20`to 23 inclusive, it ,will be seen that the guide 5 is provided' with a rectangular way 7 therein, said guide having in one of its faces a lvertical slot through which projectthe pins 1 when the bar 3 is introduced into said @way at the upper end thereof. Within the way 47 a flat curved spring 9 (see Fig. 22) whichl and causes it to iction againstthe forces the bar outwardl bear with considerable margins of the slot, thereby preventing the# bar feeding by gravity. To effect an intermittent feeding catory slide 10 is employed which is mounted upon the face of the guide near the lower end thereof and which carries upon its inner face the pawls 11 located one above the otherx upon short shafts 12 journaled in said slide. Said shafts project from the face of the slide and are embracedby coiled springs 13 the outer ends of which are secured to saidl lshafts and the inner ends to the slide. These springs exert a'pressure upon the pawls to swing them outwardly into the path 'of the pins 1. As the slide 10 moves u wardly, said pavvlsslip past the pins an ment of said slide the pin bar is carried downwardlya distance equal to the travel of said slidel through the en agement of saidpawls with the pins of sai bar. To confine the slide 10 in place during this vertical a slot 15 therein into the gui e 5.

A vertically reciprocatory. movement is imparted to the slide 10 through the medium .of a sector gear 16 (see Fig. 23). mounted upon a rock shaft 17 and meshing with a rack 18 formed on the lower end of the slide 10., The rock shaft 17 is supported in a 'bearing 19 on the frame, "asshown in Fig. 2,

Vand fixed to the opposite end of said shaft from that carr ing the sector gear 16 is a 22 of the eccentric strap 23` and confined between said lboss and an vadjusting nut 24 threaded upon the end of said pin. The

4eccentric 25 embraced by said eccentric strap is fixed to the main shaft26, which extends longitudinally of theframe of the machine of the pin bar, a reciproengage above them so that upon a downward movel movement, aI screw bolt 14 is assed through.

crank arm 20 t e outer end of which .freely 4embraces a pin 21 vprojecting from the boss As thev slide '10.is actuated, the pin bar3 is'fed downwardly for each downwardmove-` mentA of` said slide a distance equal to the spaces between the pins 1, so that the pins in said bar carrying thecajpsule bodies "28 are sequentially presented between the stripping jaws 29 embracing the guide 5, which at that loint is reduced in transverse area. to permit of the closing of the jaws around it, as shown in Figs. 4 and 5.- The rear ends of the jaws 29 are pivotally mounted-at 30. upon r-abracket projecting from a'slide block @enses j ed to slide upon the bar 32 is a head 37 car# rying the-antifriction rollers 38 adapted to engage the outer faces .of the inclined portions 39 of the pivoted jaws and close said jaws when said head is moving toward the left. Mounted 'in' the head 37 between the inner facesof' the inclined portions 39 of said jaws is a 'pin 40 which engages said inclined faces to open said jaws when the head- 37 is moving vtoward the right. Motion is transmitted to-thehead 3'7 through the medium of a connecting rod 41. One end of-the rod 41 is journaled on a pin 42 projecting .from the face of the -disk 43 fixed to the.

end of a transverse shaft 44 suitably journaled in the frame and driven from a beveled gear 45 on the main shaft which meshes .with a like gear 46 on the lowerend of a vertical shaft 47. The upper end of Said vertical shaft carries a beveled gear 48 which A meshes with a beveled gear 49 on the shaft 44. The outer end of the connecting roolA 41 passes freely through the flattened central portion of a short shaft 50 journaled at' its ends'ina bracket 51 projecting from t-he head 37. The end ofthe rod 41 projects some dist-ance through the flattened portion of said shaft and receives a coiled spring 52 confined thereon by an adjusting screw 53. A collar 54 fixed to the connectcompensates for any obstruction to the movement of the parts. IThe inwardly projecting end portions 55 of the jaw members are each provided in the inner face thereof with' a halfl round channel 56 which forms a complemen'tary lportion of a circular aperture when lsaid endl portions of the jaws areA brought together, as shown in Fig. 7. This aperture formed between the closed Jfaces of the end portions of the jaw members is adapted to embrace the pins as the jaws are closed and to strip thebodies 28 of the capsulesfrom said pins as the head 37 moves forwardyat the sametime s oving said bodies into thesockets 57 in the rotary carrier disk58, as shown in Fig. 5, wherein the 'body portions of ythe capsules, by the rotation ofl Said disk are presented 'to the trimming knife as hereinafter explained.

The j aws 29 are opened and closed through the retarded travel of the block 31 on the I bar 32 which will be explained as follows Assuming that the parts are in tlieposition. shown in Fig. 4, as the head 37 moves for-- ward .the ant-ifriction rollers 3 8 carried thereby will engage the outer faces lof the i11- clined portions 39 of said jaws and swing said jaws together uponv the pin 1- because of the fact that said jaws are pivoted to the friction block 31 which. does not start with the initial forward movement of the head the inclined port-ions'of the jaws will cause' said jaws to ope'n as said head starts to move rearwardly. When the jaw members shall have reached the limit of their outward movement, they will be locked against thev rollers 38 and a further movement of the I head 37' will cause theblock 31 to slide rear'- wardly, thereby returning' the parts` into. position for a succeeding operation.

It will be understood that durin"g the operation just described. of stripping the bodies ofthe ca xsules from the `pins and placing. 1

them in t e sockets of the carrier disks58, a similar operation is takingplace upon the opposite side of the machine with respect to the caps 59 of the capsules which are 1n like manner stripped from the pins 2 by a duplicate set of operative parts and deposited in the sockets 60 of the rotary carrier disk 61.

-The carrier disks 58 and 61 are mounted 4to rotate in opposite`directi'ons upon shafts journaled in the bearing supports 62 carried by-the frame. Upon the endof the shaft of the disk 58 is a gear wheel 63 which meshes with alike gear 64 on the shaft of the disk 6l. Through the medium of said gears said disksy are driven in unison and in unvarying relation. AIt will be notedthat said disks are oEset with respect to one another and that their inner peripheries lap. Said disks are so ositioned and are so drivenintermittently as to cause the sockets therein to register or stand in horizontal alinement at the termination of each concurrent partial rotation. Said carrier disks are driven by the gears 63 and 64 from the main shaft through the medium of the operative parts shown in Fig. 19, comprising a disk 65 fixed on the main shaft 26, and having a portion of its periphery cut away in the arc of -a circle, as shown at 66. The hub 67 of said disk is provided with a projecting arm 68 carrying an antifriction roller 69. This roller isv adapted to successively engage invioo.

The, Apoint or-ar1n of the star-Wheel having the slot in which said roller is engaged, entering 4and leaving the concaved portion 66 of the periphery, of said disk'l during said movement. As the roller A69 passes from engagement in each of the slots 70 in succession, the

circular margin of the disk moves into engagement with the curved'surface 73 between the points of the star-wheel and locks said wheel against movement during its period of rest.

parted tothe star-wheel and the pinion 74 during each complete rotation of the shaft 26, sald rotary movement being equal to one quarterof the circumference of said pinion,l

whereby there is imparted an intermittent rotationltothe gears 63 and 64 and a corresponding movement to the disks 58 and 61 carried on the shafts fof said gears, which movement is equal to one sixth of the circumference of said disks, or the distance between the capsule receiving sockets therein, said disks between their periods of rotation being firmly locked against movement in either direction. A

During each period of rest, the bodies and caps of the capsules are stripped from thev mold pins and deposited in the respective' sockets of said disks, as before described. The .next movement of said disks'carries the capsule body and cap tothe trimming mechanism whereby -said caps and b trimmed to the'desired length. The sets of trimmingy mechanism, of which there are.

two, of ldentical construction, arranged to operate simultaneously u on the caps and bodies ofthe capsules, wil be described with reference to one set only, as the description i of one set will answer for the other.

Referring now more particularly to .'12 to 17 inclusive, 75 designatesa circular knife having a flat face, which, when in operation, stands contiguous to the face'of the carrier disk, as clearly shown in' Fig. 17. Said knife is mounted upon the outer-end ofthe sleeve 76 car ing at its opposite end a pinion 77, and sai knife, sleeve, and pln'- ion are mounted to'rotate upon a journal pin 7 8'xed in the end of one of the arms of a bell-crank lever 79.v Saidbellcrank lever lis mounted upon a hollow journal 80 which f is received to oscillate within a sleeve 81 ex- By this arrangement, a par` tial rotary movement is intermittently imies are tending rearwardly from the circular face plate 82 carried at one end of the hollow shaft 8.3y which is journaled in a horizontal bearing 84, said bearing being a part of a- ,horizontally reciprocatory frame or carriage in which the trimming mechanism is mounted, comprising ,in addition to said bearing the laterally and downwardly extending hangers 85 in the ends of which is journaled the sleeve 86 carrying a gear\wheel 87, said sleeve being splined upon the horizontal v shaft 88. Forming a part of the reciprocatory^trimmer frame or carriage is a head 89 (see Fig. 14) which is adapted to slide in a rway 90 on the main frame, whereby one side of the trimmer carriage is supported and guided in its reciprocatory movement,

-the other side of said carriage being supported bythe hangers which tembrace the sleeve 86 slidable. upon the shaft 88 and rotatable therewith. The gear87 meshes with a pinionl 9.1 which is xed to one end of the hollow journal 83. lPassing through the outer hanger 185- and. through the hollow shaft 83 is a non-rotative shaft 92 having a central longitudinal, aperture 93 therethrough. The inner end of said shaft passes carries thereon a pinion 94 which meshes w1th the pinion 77 of the rotary cutter 75.

Extendlng from the end of the shaft 92 ythrough the center of the face plate 82and in axial alinement' therewith is ar pin 95 through which the aperture 93 is continued, said p'in being ofva diameter to enter the body or cap of the capsule so as to lill said cap or body' during the operation of trim' ming. Formed in said pin at the requisite distance from the e'nd thereof is a circum i ferential chan'ne196, shown more clearl in Fig. 13, in which the edge of the kni e is adapted to enter during the operation of trimming to afford a shearing action for the rotary knife when severing the end of the 2- capsule body or cap upon saidA pin. .The aperture 92 which passes through the fixed shaft 92V and through the pin 95 is for the purpose of directing an air blast there-y through from the air hose 93 which blows into the cap or bod andprevents it crawling'on the pin `whi e being cut. A circular guard 97 is located adjacent the face of thecarrier disk against which the closed vends of the lcaps or bodies bear to prevent their being blown from the pin 95 by the air blast during the operation of trimming and to 'maintain them in proper position in the y socketof the carrier disk Whlle passing from the stripping jaws to the trimmer knife. It will be noted that in order to permit the pin 95 to enter the cap' or body of the capsule preparator to the operation of trimming, theA knife 5 must be moved from contact with said pin except duringvthe period said knife is in actual'operation. To actuate the;

bell-crank lever 79 and carry the knife from contact with said pin, a cam 98 is employed which is mounted on the sleeve 86 to rotate therewith and which is so ositioned as to engage the free end of the ell-crank lever,

as shown in Fig. 15, to swing said lever on its fulcrum and raise the knife from the pin 95 during the time said knife is not-in operation, said cam passing from engagement with the end .of the bell-crank lever after the pin shall have entered the capsule to permit the knife to'drop -upon the protruding end of the capsule part as said knife starts tb rotate and to travel in 'a circle. around said pin in the operation of trimming. A spring 99 (see Figs. 15 and 16) is attached .to the end of the bell crank lever 79 and returns the knife into working relation with the pin 95 when the cam 98` passes from engagement with Isaid lever. A stop pin 100 projecting from the face plate 82 arrests the return movement of the bellcrank lever to prevent the knife being drawn into forcible engagement with the bottom of the channel 96 in said pin. i

A sliding movement in one direction is imparted t'o the carriage carrying the trimming mechanism by means of the cam disk 101 mounted" on the main shaft 26 and adapted to engage with the high point there-4 of, as the main shaft rotates, an -antifriction roller 102 onl an arm 103 (see Fig. 14)

.extending downwardly from the carriage of the trimming mechanism, whereby saidcarriage and the mechanism mounted therein is moved to the left to withdraw the pin 95 from the body or cap of the capsule and the cutter 75 from the face of thecarrier disk. The coiled spring 104 which is attached to the arm 103 of the .trimmercarriage, slides said carriage inthe opposite direction when the higli 'point of the cam 101 passes from engagement with the anti-v friction roller 102. It will be noted that said spring 104 is attached at its opposite ends to the arms 103 of the two sets of trimming devices, whereby both sets are simult-aneously actuated by said Springto ret-urn them into working relation with their respective carrier disks at the proper time.

An intermittent rotary movement is im-A parted to the shaft 88 b-y means of'a mutilated gear Y 105 mounted onthe shaft 26 and Imeshing with the pinion 106 on shaft' 88.

The teeth of the mutilated gear 105 are formed upon onehalf of the periphery thereof and contiguous to said gear on the shaft 26 is a semicircular plate 107 whose periphery is concentric with the axis of the shaft 26 and is Vadapted to pass into engagement with the antifriction rollers108 on the face of thepinion 106, at the time the teeth on the mutilated gear pass from engagement with the teeth of said pinion,

` whereby the shaft 88 is locked at the end of neach period of rotation. There are a- 'cause of the fact that the shaft 92 does not rotate and that the pinion 94 thereon meshes with the pinion 77 on the sleeve of the cutter 75, said cutter is caused to rotate about its axis as it travels in a circle about the axis of the pin 95, thereby imparting thereto a planetary movement which renders. it effective in severing the projecting end of the cap or body of the capsule, said effectiveness being increased .by the fact that a two to one gear'is employed for 'rotating the hollow shaft 83, whereby the knife is caused to make two complete revolutions around the pin 95..

The parts are* so timed in their operation with relation to the intermittent movement of the carrier disk that during each period of rest ofsaid disk a cap or body is introduced into'a socket thereof and a cap or body previously introduced is trimmed,the disk'in its movement'presenting in succession an empty socket to the stripper to receive a capsule vcap orbody and a lled socket to the trimming mechanism that a cap or body may beacted upon thereby. At the cessation of each period .of movement imparted to the carrier disk, a capsule cap or body is presented in alinement with .the pin 95 at which time the slidable carriage in which the trimming .mechanism is mounted is moved toward said disk so as to cause said pin to enter saidv cap or body and the rotary knife to stand adjacent the face of body, a stripper is provided in the form of a laterally projecting 'arm 109, (see Fig. 17) which extends from the end of a shaft 110 mounted to slide longitudinally through the journal V80 which forms the fulcrum of the bellecrank lever 79, said shaft carrying upon its outer end a collar 111 between which a-nd the rear face of the rotary plate 82 isconfined a spring 112 which surrounds the projecting end of the shaft 110. As the carriage of the trimming mechanism is moved away from the face of the carrier disk after the' operation of trimming, the fixed arm 113 which projects from the frame in the path of the collar 111 on the end of the shaft 110, will prevent said shaft 110 returning with the carriage, whereby the pin 95 is caused to draw across the arm 109 and strip from the pin the trimmed end portion 108 of the capsule part.v The spring 112 which is compressed during this movement, 'retracts the shaft 110 when the carriage again moves forward to place the stripping arm 109 in position for a Vsucceeding operation.

From the sets of trimming machines, thev caps and bodies of the capsules in their respective carrier disks are presented to the joining device, at which time the sockets in the lapping facesl of the carrier disks'58 and 61 are caused to register or stand in the samehorizontal plane, as clearly shown in- Figs. 8 to 11 inclusive, wherein Fig. 9 illustrates the position of the parts' at the 1nception of the joining operation, showing the open end of `a body of a capsule in a socket of thei disk 58, registering with the open end of a cap in a socket in the disk 61, in which position'of parts the reciprocatory and pivotally mounted spout 114 isactuated, by means hereinafter explained, to cause the projecting foot 115 thereon to engage the end of the cap 59` and force said cap inwardlyonto the open end of the body, as shown in Fig. 10. This operation only partially completes the joining of the capand body, and to complete the joining operation a reciprocatory plunger 116, actuated by means. hereinafter explained, moves against the projecting end of the body and `crowds it into the cap, as clearly shown in Fig. 8, Sheet 4. At this time the spout is so actuated as'to cause the foot 115 thereof to pass from in front of the socket in the disk 61 in which the capy is confined land permit the plunger 116 whichcontinues its forwardmovement to discharge the completed or joined capsule 1,17 into the opening of the spout 114 through which it is conlveyed away.

It will' be noted on referringto Fig'. 4,l

Sheet 4, that the sockets 57 in the disk 58 are oounterbored, as shown at 118, to facilitate the passage of the -end of the cap upon .the end of the body' held therein.

The plunger 116 is actuated to retract it from the registering sockets in the carrier disks, after discharging the joined capsule,

by means of a cam wheel 119-on the mainl ing said plunger between said bearing and the collar 125 on the inner end thereof is a compressible spring 126. As said plunger is retracted by the cam 119 this spring is compressed so that when the high point of said cam passes` from engagement with the ant-ifriction roller 120 in the lever 121, the force of said spring will returntlie plunger and cause it to discharge the joined capsule l from the registering sockets in the carrier disks. The operation of said plunger isr so timed with respect to the intermittent move 'ment of the carrier disks that an actuation thereof to eject the joined capsules, occurs during each period said disks are at rest.

- The spout 114 is caused to reciprocate in successively presented to and withdrawn from the face of the carrier disk 61. A'tilting movement in addition to the horizontal reciprocatory movement is imparted to the spout through the medium of a crank arm 129 (see Fig. 23) mounted on the rock shaft 17, said crank armlcarrying a pin 130 which engages in a slot 131 on the under side of said spout at its lower'end, Said rock shaft is so actuated as to tilt the spout on its pivot 128'at the instant the cap and body of the capsule are joined, as shown in Fig. 8, Sheet 4, so as to move said foot portion of the spoutx from in front of the registering sockets in the carrier disks and. present the spout in alinement therewith to receive the discharged capsule, as shown in Fig. 11', Sheet 5.

After lthe capsule caps andbodies shall have been stripped from the mold pins, it is necessary before said pins are again dipped in the gelatin bath to mold additional caps and bodies thereon, that they be oiled or greased to prevent the caps and bodies sticking thereto. In order to obviate an extra handling of the4 pin barsfor this purpose, we have provided two mechanically actuated pin easing devices which operate upon the plns of the caps and bodies respectively t o grease them after the. caps and bodies have been stripped therefrom and while the pin bars are passing vertically through the machine. The description of the construction and operation of thepingreasing devices will be -made withA reference to one of said devices, only, because of the -fact that said devices are identical and operated-in unison in exactly the same manner. On're- -ferring toFigs; 1 and 2,- it will be seen that mounted upon` the pin 42 of theA disk 43 on which thel connecting rod 41 is journaled, is also journaled alpitman 132 pivotally connected at 133 with one'end of a reciprocatory rod 134 whose opposite end is mounted to slide in a guide 135 and is provided von 153 are placed between the flaring outer end the downwardly traveling pin bars, 4are vtain said head in said socket.

its under face with-rack teeth 136 which mesh with the-teeth of a sector gear 137 mounted upon one end of a transverse rock -shaft 138. The opposite end of saidgrock shaft carries` a sector-gear 139, shown by dotted lines in Fig. 2,'the teeth of which mesh with the teeth 140 on the upper side of a longitudinally reciprocatory and non-rotai .tive rack 141 which is supported to slide in the end of a downwardly extending bracket 142.

Journaled in the reciprocatory rack 141A within the head 146 is a socket plunger 149 having a Haring opening 150 at the outer end thereof and engaged at its rear end by a compressible spring 151. Packing 152 saturated with grease is placed in the socket of the plunger 149 `:and greased ,packing rings of said plunger and the inclined annular wall 148 surroundingthe opening through the end of said head.4 A spring latch 154 is mounted upon the socket member 145 and is adapted to engage an annular shoulder 155 upon the cylindrical head to detachably re- The' rotary and reciprocatory shaft 143 carrying the greasing head 146 is sopositioned as vto'present said head in alinement with the vertlcal row of pins carried' in the pin bar andl is so timedin its movement with respect to the operation of the machine as to move forward when the pin bar is at rest. In this forward movement the head. passes over the pin which enters the aperture in the end thereof, causing the greased packing within the head tov embrace the pin, which as the head rotates, thoroughly greases not onlythe body of the pin, but the end thereofe- As the head withdraws from the pin,: the bar carrying the pin moves downwardly to present a succeeding pin in the path of said head which again moves forwpard to embrace said succeeding pin, the operation beingintermittently timedsoI that thefpins are sequentially greased as .the pin bars move downwardly through the machine.
